I have linked up two topics that might help explain in more detail how I use tracking codes and what I am ultimately aiming for
linking clients with expenditure
and using expense accounts and tracking codes
But to save you reading the entire posts to get the gists of what I was looking for:
In short, I want to track income/expenditure by divisions - IT Support, Sales (hardware and Software), Website design etc. I do this by creating tracking codes for each division and I have now set purchase invoice items to be linked to whatever division they are relevant to. With the sales (Software and Hardware Division), I have broken that up into Software Sales, General Sales, Networking Sales, Computer Sales, Laptop Sales Tracking codes and I want to assign laptop inventory to the Laptop Sales Tracking code. The idea being so that I can see how much income is generated through laptop sales, network sales, software sales etc!
As mentioned in one of the topics linked here, you suggested that you might make a master tracking code for the divisions and a projects tracking code for projects as one of the issues both myself and other people have come across is a need for multiple tracking codes for the same item.
